Answer:
Check the image below for the answer. I have successfully dragged each label to the correct location. Also, I have labelled the endothermic and exothermic reactions.
Explanation:
The first diagram (by the left) is an endothermic reaction. In this reaction, the products are higher in energy than the reactants. Heat/Energy is absorbed in this reaction and enthalpy is positive.
In second diagram (by the right) is an exothermic reaction. In this reaction, the reactants are higher in energy than the products. In this reaction, heat/energy is released.
